Question

How does NAT (Network Address Translation) work, and why is it essential for modern networks?

Expert Solution

Step 1: Define NAT

A networking technology called network address translation, or NAT, enables several devices connected to a local network to communicate with other networks, such the internet, by sharing a single public IP address.

In order to improve security and preserve public IP addresses, NAT translates private IP addresses used within the local network to a single public IP address when interacting with external networks.
